To all whom it may concern: I Be it known that we, \VIL IAM AoAMs DELANOand ELEANOR ROBSO'N BELMONT,

citizens of the .United States,and residents,

respectively, of the city-of'New York,,bor-

ough of Manhattan, in the. county and State of New York, and Hempstead,i.n the county of Nassau and State of New York, have in- I desktelephone. withthe attachment applied vented anew and ImprovedReceiver-Hold- 10 ing Attachment for Telephones;'of 'wh1 ch scription. li

Thislinventionrelates to attachments to telephones for holding the.telephone "re the following is a full, clear, and exact de- '1'5 ceiverin suchrelation to the transmitter that a person can usethe telephonewithout the necessity of supporting the: receiver to the"ear by thehand,' asis now commonly necessary, and as result both hands will.

i 'shownqn connection-With a desk type of telephone-but .it is to beunderstood that befree for any desired'employment during a.telephoneintercourse,

Theinvention has for its general ob]ects to improve andsimplify'theconstruction of deviceslof the character referred to so '25as to be reliable and eflicient-in use, com- .paratively'inexpensive toconstruct, and so designed that they can be appliedto.v the arious typesof telephones 'andby persons" ,../'of ordinary intelligence. v

A more specific. object of the invention 'is j "the provision ofareceiver holding attach ment for telephones in which. the"attachmenti-embodies a clamping ring or clip which is applied to andclamped on the body.

Siof the" telephone transmitter, and project-'.'

ing' laterally from the clip or ring are sprlng aws so shaped as toeffectively 'hold the grip portion of the receiver, whiletheldia"phra'gmportion of .the receiver will be so 40 ;rel ated,to thetransmitter that While the re-. ceiver is adjacent the" ear of the userthe,

mouth willbe in suitable proximity to thetransmitter, so that the voicecanbe'-directed into the latter, and as the \receiveris,

- 4.5 by means 'of the attachment, supported on the body of thet'ransniitterpthe hands .of the person using the telephone are left freefor .various purposes, and the tiresome act' ofv holding the receiver-t0the 'ear is obviated. i ,'With. such objects in View, and others whichwill appear as the description pro- 7 ceeds, the invention comprisesvarious novel features of construction and arrangement Specification ofLetters Patent; Application filedFebruary 11, 1915. 4 Serial No.. 7-,5e3

ticularity inth'e following-description and and wherein similarcharacters of reference indicate corresponding parts inall the PatentedFeb; 1, 191;6 1 I 'of parts suclr'as willbe setforth with par- I views,Figure' l is a-perspective view" of a to the transmitter body, and thereceiver being shown by full lines supported onv the switch hook, and bydotted lines on the-at :tachment; Fig. 2 is a plan'vie'w ofjthe at-.

tachment, showing the same supporting the receiver of the telephone; Figz-B is a per .spe'ctivefiview 0f the attachment removed; and Fig. ,4is a vertical section .through the clip or clampingringof-the'jattaehment;

In the pres'ent instance the attachment it. is'applicable to otherforms.

Referring to the drawing, A designates a' transmitter is the attachmentC, whichcon stitutes the subject'matter of'the present invention. The'purpose'. of this attachment is to support the' receiver, when the.telephoneis in use, in such a manner that a con versatlon can beconducted through the telephone without the .user having to hold thereceiver in the hand; as is now commonly necessa'ry. When the attachmentis not in use the receiver A is supported in the usual a manner on theswitchfork- 1 of the telel- "phonel. j a 1 r The attachment C comprisesan attaching ring or clip 2 which is made intwo semi-f and'at 6being-provided with outwardly ex tending lugs .7 and-8 which 'areprovided vice. tend to spring apart so 'thatthe ring will body of thetransmitter B, and whenthe ring is properly i applied, the screw .9 isturnedso'asto contractthe ringand thereby clamp the samecircumferentially around. the body of the'transmitter. Theringis made ofsheet metal, and thefront edges of the members 13 and 1 are bent into.internal circular parts '3 ands riveted together at5, I

with a screw -9 or equivalent tightening de-. I The semi-circularmembers 3 and 4' be of large enough diameter to slip on the v Adams-1'filai'i' 'es 10 which en age the front face Z) of a b the transmitterbody' and determine the ire )er )OSltlOIllll of the 1111 on the latter.

the attaching 'ingQ is formed with later all I are ectin 11 iin aws 3and 4P, 0

. r a c l positely bowed so that they can obtaina firm grip on thehandle portion aof the receiver A. The free extremities of the jaws arebackwardly curved into lips 3 and 4;, which lips are spaced apart so asto constitute an, open mouth somewhat smaller than the diameter of thegrippoi'tion (a of the receiver A, and preferably, althoughnotnecessarily,

the lower lip 4 projects somewhat beyond the lip 3" whereby theinsertion of the re- -eeiver is facilitated. In inserting the receiverthe same'comes into contact with the two lips, and these spring apart asthere- 'CQIVBI' is forced into the jaws, and as soon as the receiver isfully inserted the jaws close, by means of their resiliency, on thereceive-r and firmly hold the same. These jaws have considerablewidth soas to providelarge bearing surfaces for the receiver. The jaws 3 and 4are preferably integrally con-c nected .with the sections 3 and 4 of theattaching riiigQ, and thejaws are united with their respective ringsections by fiat portions 12 whiclrare brought'together andfastened'byarivet13.

. VVlien'the telephone is in use the receiver is held thejaws, as shownby dotted lines in Fig.1, and the relation of the-effective part of thereceiver to the transmitter is such that voice sounds canibe reliablyreceived and transmitted. The placing of the .re-

. ceiver'in the jaws and the removing'of .the

receiver therefrom requires-but little effort and can be' done with onehand.

rom the ,foregoing description taken connection with the accompanyingdrawing, the advantages of the construction and method of operation willbe readily understood bythose skilled in'the artto which the inventionappertaiiis, and While we have de-v scribed the principle ofoperation,.together with the device which wenow consider to be the bestembodiment thereof, we desire to 4 have it understood that the deviceshown is merely illustrative, and that such changes. may be'made whendesired as fall within the scope of the appended claims. Having thusdescribed our invention, We

claim as new and desire to secure by Letters Patent: v I

1. A telephone attachment comprising a clamping ring for application toa transmitter body, said ring "being provided with an internal flangefor engaging the front of the body to determine the proper positioningof the ring and also for stiffening the said ring, and a pair of jawsintegrally connected with the ring and extending laterally therefrom tohold a receiverduring the use of the telephone to which the attachmentis applied. i 2. A receiver attachment for telephones,

comprising a clamping ring expandible and contractible, said ring havingat its front edge an internal flange adapted to engage the .front faceof a telephone transmitter,

and laterally projecting spring jaws for holding a receiver, the freeends of the jaws being spread apart, and the lower jaw projecting beyondthe upper jaw, said flange insuring the placing of the attachment on thetransmitter in a position with the longer jaw lowermost When the jawsproject from the left'of. the transmitter.

3. A receiver holding attachment for telephones, consisting of twosections, each section being made of a single strip ofmetal and bentinto a semi-circular part, and a bowed jaw, the jaw, being unitedv withone I extremity of the semi-circular part by a flat portion, and theoppositeextreinity of the semi-circular'part being formed into. anapertured lug,.a fastener for permanently securing the flat parts of thesections together, and a tightening device passing through the aperturedlugs, said semi-circular parts being formed with internal flanges forinsuring the proper positioning of the attachment on the body ofatransmitter and ROBERT F; MARTIN, "ADoLrH- C.
